In this research, a constrained cellular automata (CA) model based on Artificial Neural Network (ANN) is developed to simulate and forecast urban growth. As we know, many factors impact urban growth, and relationships among them are complex and non-linear. In geographic CA research, models with different rules and symbology have been developed to simulate those relationships. Yet, in previous d...
Objective: To improve the reliability of complex urban public transportation network. Methods: Establishing the reliability evaluation system of urban public transportation network. Process: The paper introduces the development of urban traffic construction, describes the characteristic parameters of complex networks, and establishes the model of the reliability evaluation index system of compl...
Background and purpose: Household drinking water treatment devices are becoming commonplace to improve the quality of drinking water, remove odor, taste, turbidity and color, pathogenic organisms, toxic chemicals, organic matter, and carcinogenic pollutants. This study aimed at investigating the Heterotrophic plate count (HPC) in drinking water and possibility of biofilm formation in household...
There are many evident that people are more interested in walking in attractive urban spaces and inappropriate physical and psychological condition can reduce their presence in a remarkable amount. The current research investigates the influence of physical design and psychological elements and their criteria on selective physical activity and specifically walking in urban public spaces. Howeve...
Background and objective: Water supply networks are among the main and vital infrastructures of any city, therefore maintaining the safety of water supply facilities and considering necessary arrangements during encountering the critical conditions is among the main concerns of officials related to security issues of any country. For this purpose, investigation of these facilities in terms of p...
ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. landscape planning can play a role in mitigating the effects of human-related activities. one element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...
guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of intelligent transportation systems (its). nowadays, many complex systems can be controlled by using multi agent systems. adaptation with the current condition is an important feature of the agents. in this research, formulation of dynamic guidance for vehicles has been investigated based...
Much of the socioeconomic life in the United States occurs in its urban areas. While an urban economy is defined to a large extent by its network of occupational specializations, an examination of this important network is absent from the considerable body of work on the determinants of urban economic performance. Here we develop a structure-based analysis addressing how the network of interdep...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
